Relentless advances in information technology are constantly transforming market dynamics of the retail industry. RFID is an emerging innovative technology that can reduce labor costs, improve inventory control and increase sales by effective business processes. Apparel retailers need to recognize the benefits of RFID and identify critical success factors. By focusing on apparel retailers, this study attempts (1) to identify the reality of RFID associated with benefits; and (2) to prospect the implementation of RFID in apparel retailing. We conducted a focus group interview with selected six panels who were experts of retail industry in the United States to obtain data regarding RFID attributes. Content analysis was used to generate related excerpts and classify 31 attributes of RFID benefits from the meaningful 173 responses. For experience of RFID, retailers were familiar with RFID technology and expressed the belief that RFID basically would support an existing retail system for speed to markets. However, retailers addressed the level of experience with RFID technology that they were still in the early adoption stage among few innovative companies. The content analysis identified five dimensions of RFID benefits for apparel retailing: Visibility and Velocity, Revenue Enhancement, Customer Service, Security, and Employee Productivity. This result lends support to the belief that RFID has a significant potential to streamline supply chain management, store operation and customer service for apparel retailing. This study provides intellectual and managerial implications far practitioners and researchers by postulating the effective use of RFID in the apparel retail industry.

Objective : Postpartum depression(PPD) was known to be caused by many factors including various psychosocial risk factors. This study was performed to identify the psychosocial risk factors for ppd, preliminarily in Korea. Methods : A group of 119 postpartum women, each of whom was at 6 to 8 weeks after delivery was identified at the time when they visited to the child health clinic or postnatal check-up clinic. The risk factors were surveyed by the self-reported questionnaire. The items of questionnaire were consisted of known risk factors in other studies and other possible stress-related factors. PPD was assessed by the Edinburgh Postnatal Depression Scale(EPDS) and the degree of postpartum depression was determined by its score. Results : 16 women(13.45%) in the high risk group were diagnosed as PPD among the 119 women. Risk factors including past experience of depressive symptoms and low level of marital satisfaction were founded more frequently in women in the high risk group than in the low risk group. The score of EPDS was significantly high in the group who experienced depressive symptoms in the past, anxiety or depression during pregnancy, stressful life event during the period of recent pregnancy and postpartum, and who had low level of marital satisfaction. There was a positive correlation between age and the score of EPDS. However, the postpartum depressive symptoms were not influenced by the level of education, job, retirement due to pregnancy and delivery, wanted or unwanted pregnancy, delivery method, feeding method, the hospitalization of infant, expected and real gender of infant. Conclusion : These results suggest that PPD is quite frequent at postpartum period. Various risk factors contribute to the development of PPD. If clinicians pay attention to the risk factors of PPD and give appropriate psychiatric intervention to the mothers during pregnancy and postpartum, it will be easy for the clinicians to recognize and treat PPD in the early stage.

Literacy on food additives of elementary school teachers (ET) and nutrition teachers (NT) could be influential factor on safe dietary education for school children. Therefore, the perceptions and information needs on food additives were surveyed from 351 elementary school teachers and nutrition teachers in metropolitan area of Korea, and the basic data for the promotion of risk communication on food additives among them were obtained. Compared to ET who consider 'taste' (39.1%) as the most important factor while purchasing food, NT considered 'safety' (68.1%) first (p < 0.001). Among the food labelling items, the level of understanding on food additives was the lowest both in ET (3.53) and NT (4.17), and NT showed better levels of understanding overall on food labels. Both ET and NT regarded hazardous factors of food as environmental pollutants, foodborne pathogens, and food additives in order, and tended to select 'no additives' or 'no artificial color' products while purchasing processed food. Although NT answered that they know all food additives had been passed the evaluation of safety and effectiveness tests (100%) and have standards of use (81.9%), majority of them (87.5%) believed the consumption of food additives are harmful on human health. ET (75.2%) also regarded food additives as dangerous materials. Above results suggested the necessity of proper and enough risk communication for both ET and NT. Both ET and NT wanted to have information on the safety or hazard of food additives. Most preferred media to get the information on food additives was TV (3.80) among ET and lecture (3.65) among NT. ET and NT trusted hospital, research institution/universities or the personnels working in these institutions as the provider of information on food additives. The result that the trust levels of ET and NT on government were relative low suggested the weakness of risk communication in Korean government. Although ET and NT answered that they do not trust mass media, their behaviors were affected by them such as reading food labels in ET (39.4%) and reducing the consumption of food additives in NT (50%). They also indicated mass media's problem of sensitive approach on food additives and asked the urgent reaction of government by providing sound information through experts on food additives. Above results revealed that ET and NT have different perceptions and information needs on food additives, therefore, proper risk communication should be provided for them to serve as dietary educators for elementary school children.

Purpose: This study was performed to investigate burden, job satisfaction and quality of life of nurses who take care of cancer patients. Methods: The subjects were 237 nurses working at the oncology unit of hospitals with over 500 beds in Seoul and Gyeonggi-do. Data were collected using questionnaire from the February to March, 2005. Data were analyzed through t-test, ANOVA, Pearson's correlation coefficient and stepwise multiple regression using SAS. Results: 1. The item that showed the highest level of burden was 'I feel limited even if I make efforts to reduce patients' pain. 'Burden was high in those group both who were younger than 35 years old and who had clinical experiences caring cancer patients for $3{\sim}4$ years. 2. The item that showed the lowest level of job satisfaction was 'the possibility of promotion'. Job satisfaction was high in those group both who had a spouse and were head nurses or incharge nurses. 3. The item that showed the lowest level of quality of life was 'I am physically exhausted'. Over 35 years old who had a spouse, and over 2,000,000 won monthly income made a high score in the quality of life. 4. There were negative correlations among burden, iob satisfaction and the quality of life. 5. The major factor affecting the quality of life was burden. Conclusion: The results of this study are expected to be utilized as basic data for developing support system to improve nurses' work conditions and quality of life.

Purpose : The objectives of this study was to evaluate the correlations between the indices of insulin sensitivity using fasting glucose and insulin level, and the body fat mass measured by bioelectrical impedance analysis(BIA) and dual energy X-ray absorptiometry(DEXA), and to determine the clinical usefulness of insulin sensitivity indices when obese children were followed up. Methods : In this study, 28 simple obese children and adolescents were included. Anthropometric data including body weight, height, obesity degree(OD), body mass index(BMI), and waist-to-hip ratio were collected and then body fat mass was measured by using BIA and DEXA. For metabolic data, 12 hour fasting serum glucose, insulin and lipid profiles were measured and indices for insulin sensitivity(G/I ratio, $log_{insulin}$, HOMA-IR, $log_{HOMA-IR}$, QUICKI) were calculated. Results : BMI had a higher correlation with insulin sensitivity indices than OD(G/I ratio, -0.463 vs -0.209; $log_{insulin}$, 0.417 vs 0.196; HOMA-IR, 0.301 vs 0.238; $log_{HOMA-IR}$, 0.403 vs 0.198; QUICKI, -0.451 vs -0.224). But OD had a higher correlation with body fat mass measured by BIA and DEXA than BMI(BIA, 0.612 vs 0.316; DEXA, 0.667 vs 0.512). The G/I ratio was correlated with body fat mass in BIA(r=-0.420, P<0.05) and DEXA(r=-0.512, P<0.01), percentage of body fat(percentage of fat) in BIA(r=-0.366, P<0.05) and DEXA(r=-0.449, P<0.01). HOMA-IR was only correlated with body fat mass in DEXA(r=0.341, P<0.05). Conclusion : This study revealed that G/I ratios had a statistically significant correlation with anthropometric obesity indices(OD and BMI) and also had a correlation with both body fat mass and percentage of fat. These results suggest that G/I ratios could be used as useful index when obese children and adolescence are followed up.

Purpose : The use of growth hormone(GH) to promote growth in normal short children without classical GH deficiency is controversial. Numerous foreign studies have shown the effects of GH therapy in children with idiopathic short stature(ISS) whereas few has been interested in Korea. Therefore, this study is designed to investigate the effects of GH therapy on ISS by observing correlations and changes among various growth parameters such as, insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding protein-3(IGFBP-3). Methods : This study was conducted retrospectively with 15 children with ISS in Chungbuk National University Hospital in Korea. Mean age was $11.44{\pm}2.81$ and the children were treated with 0.66 IU/kg/wk dosage of GH for 1 or 2 years. Also, the growth parameters before and after the GH therapy were observed. Results : Height standard deviation score(HT-SDS) was increased from $-1.85{\pm}0.70$ to $-1.58{\pm}0.56$ at 1 year and to $-1.21{\pm}0.37$ at 2 years after GH therapy. Predicted adult height standard deviation score(PAH-SDS) was also increased from $-2.10{\pm}0.52$ to $-1.67{\pm}0.59$ at 1 year, and to $-0.96{\pm}0.60$ at 2 years. Serum IGF-I and IGFBP-3 levels were significantly increased after 1 year and marginally increased after 2 years of GH therapy. Conclusion : It is concluded that GH therapy has growth promoting effect. The significant increase in IGF-I and IGFBP-3 levels during the GH therapy suggests that IGF-I and IGFBP-3 are useful predictors of response to the use of GH therapy. It is expected that larger patient samples would provide more reliable information about the effect of GH therapy.

Objective: To evaluate the impact of endometriosis on IVF-ET cycles and to compare IVF outcomes between stage I/II and stage III/IV endometriosis. Methods: We analyzed 697 patients (1,199 cycles) with endometriosis (stage I-II:638 cycles, stage III-IV: 561 cycles) and 325 pts (459 cycles) with tubal factor as controls between January 1994 and April 2004. Pts with endometriosis were diagnosed by laparoscopy and medical and surgical treatment were done in 353 cycles (55.3%) and 466 cycles (83.1%) of stage I-ll/stage III-IV endometriosis. Cycles with age>35 years or FSH>20 miU/mL or severe male factor infertility were excluded. Results: The number of retrieved oocytes ($9.97{\pm}7.2$ vs. $13.4{\pm}7.9$ (p<0.0001 )), total number of embryos ($6.5{\pm}4.8$ vs. $9.1{\pm}5.6$ (p<0.0001)), and good quality embryos ($2.43{\pm}1.6$ vs. $2.74{\pm}1.7$ (p=0.013)) significantly decreased in stage III-IV endometriosis than in control. But pregnancy rate of stage III-IV endometriosis was comparable with control (35.7% vs. 36.8%). Fertilization rate and number of total embryos were lower in stage I-II endometriosis than in control ($64.8{\pm}22.9$ vs. $70.8{\pm}20.8$ (p<0.0001), $7.6{\pm}5.0$ vs. $9.1{\pm}5.6$ (p<0.0001)). In patients with medical and surgical treatment of endometriosis, pregnancy rate and live birth rate was significantly lower in stage I-II than in stage III-IV endometriosis (29.2 vs. 36.2 (%), p=0.045, 23.9 vs. 31.5 (%), p=0.043). There was no difference in the mean age, but the duration of infertility was significantly longer ($56.5{\pm}26.3$ vs. $46.9{\pm}25.8$ (mon), p<0.0001) and fertilization rate was lower ($64.7{\pm}23.3$ vs. $70.5{\pm}22.7$ (%), p=0.001) in stage I-II than stage III-IV endometriosis. Conclusion: We suggest that IVF should be considered earlier in patients with minimal to mild endometriosis because of significantly decreased fertilization rates.

Purpose : We compared the pain reducing effect of orally administered glucose solution with EMLA cream and pacifiers during venipuncture in newborn infants. Methods : Fifty newborn infants(30 prematures) were enrolled in this study. We performed these four pain-reducing methods to all infants in serial order. Group A(control) did not receive any treatment; to group B, EMLA cream was applied on the skin for 1 hour; group C(or D) received 10 percent(or 30 percent) glucose solution orally; group E used pacifiers. Symptoms and signs associated with pain at venipuncture were measured with the Premature Infants Pain Profile(PIPP) scale. Results : There was no significant difference in the PIPP scores between preterm and fullterm infants. The mean PIPP scores of groups were A : $12.5{\pm}2.5$, B : $10.1{\pm}2.6$, C : $9.4{\pm}2.0$, D : $6.5{\pm}2.1$ and E : $8.7{\pm}2.3$; the mean scores of groups B, C, D and E were significantly lower than that of group A(all, P<0.001 except B(P<0.05)), and the mean score of D was significantly lower than those of B, C and E(P<0.001, P<0.005, P<0.05, respectively). The percentages of patients with PIPP scores above 6, which means pain, were A : 100 percent, B : 82 percent, C : 56 percent, D : 40 percent and E : 70 percent. The percentages of patients with PIPP scores above 12, which means severe pain, were A : 72 percent, B : 30 percent, C : 22 percent, D : 0 percent and E : 14 percent; that of group D was clearly lowest. Conclusion : These results support the use of oral glucose solution, EMLA, and pacifiers for pain reduction as effective intervention at venipuncture in newborn infants. The most effective method was a 30 percent oral glucose solution.

Purpose : The objectives of this study were to investigate the causes of chronic cough and to establish the appropriate diagnostic approach to chronic cough in children. Methods : One hundred and thirty two cases of chronic cough were prospectively evaluated. They visitors to pediatric chronic cough clinics at Kang-nam saint Mary's Hospital of Catholic University from August 2000 to July 2001 for 12 months. Careful history taking by questionnaire, physical examination, radiologic studies of chest and sinus, hematologic and immunologic studies, allergic skin tests, and methacholine challenge tests were performed. Color doppler(CD) ultrasonography were performed and compared with simultaneous 24 Hr. esophageal pH monitoring to diagnose gastroesophageal reflux disease(GERD). Results : Age distributions were demonstrated that nine in infants, 82 in early childhood, 38 in late childhood, and three in adolescence. Common causes of chronic cough were bronchial asthma in 40 cases, chronic sinusitis in 22 cases, GERD in seven cases, bronchial asthma combined with sinusitis in 28 cases, bronchial asthma combined with GERD in 14 cases, psychogenic cough in two. cases, foreign body in one case, chronic bronchitis in one case, and bronchiolitis in one case. Comparing with 24 Hr. pH monitoring, sensitivity, specificity, positive predictive value and negative predictive values of CD ultrasonography were 88%, 69%, 85 %, and 73% respectively. Conclusion : The most common causes of chronic cough in children were bronchial asthma, sinusitis and GERD in order. We suggest that CD ultrasonography can be used as a good, convenient screening method for patients with suspected GERD in outpatient settings.
